Then john realized that nobody had done a proper background check on the guy. One of other engineers in the company had recommended him and he
seemed nice. They had been in a hurry to hire someone for the position so they didn’t check this background very carefully. Suddenly, he had a bad feeling. immediately, he used his smartphone to check the company’s bank accounts. To his horror, he found that a large amount of money was missing from one of his accounts. There had a large withdraw earlier that morning,
Well, what did you think of my presentations.
Did you want me to be frank? I know we work very hard on it.
Yes, give me to it straight. I have my own opinion too. But I appreciate your comments and suggestions.
You said you had your own opinion about it. so how do you think of them.
I thought it went ok at first. But I could feel there were some bad transitions(过渡).
I think I spent too much time on some slides and didn’t express them well.
I agree on most points. But to me, it was flat. 5 minutes into it I had a hard time paying attention.
But it seems so easy for you.
For me, I look at the faces in the audience. I watch their expressions. I really try to communicate with them. Once I do that, it comes naturally, because it becomes real communication.
You seem to enjoy it.
Well, I’m always nervous too before I get started. But once I contact with the audience, I’m ok.
So contacting with the audience is the key. Focus on them and not me, right? Yes, well put. In fact, if you do that, you will have to adjust your presentation. It has to flow like in a read conversation. We have to respond to each other. And

They highlight agriculture which is heavily dependent not only on gasoline to fuel machinery, but also on the petrochemicals necessary to manufacture synthetic(合成的) fertilizers and pesticides. Without these petrochemicals, crop yields would be only a fraction of what they are today. To assume that an abundant source of renewable
energy will address this challenge is to ignore the vital non-fuel uses of petrochemicals.
Then there is the challenge posed to the current levels of mobility. As a fuel, gasoline is unrivalled(无敌的) in its portability. Electricity requires bulky batteries and hydrogen is notoriously difficult to store. Biofuels might seem like

Petrochemicals are used to manufacture pesticides, which are good for agriculture.
The meaning of catch 22
One of the most interesting books of the 20th century was the novel, Catch 22. In the novel, the term has nothing to do with catching anything. It has a much
deeper meaning, and it describes a kind of logical conundrum(难题) that’s worth exploring.
First, it’s important to put the phrase into c ontext. In the novel, a group of American bomber pilots is on an island in the Mediterranean. They face death almost every day when they fly their bombing missions. Many have already
Yossarian told him to ask one of the other pilots, Clevinger, to tell him how crazy he was. “There is no point. He’s crazy.” The doctor replied.” Crazy people can’t decide whether you are crazy or not.”
“Clevinger isn’t crazy! he’s one of the sanest pilots here.”
“So he’s obviously out of his head,” said the Doc. “He’s got to be close calls he’s had.”
“well, if he’s crazy, why don’t you ground him?”
“I can’t unless he asks to be grounded. That’s part of the rule.”
“So all he has to do is ask?”
has helped humans survive, it makes it more difficult to control infectious diseases. As conditions change, the organism which caused these diseases adapt and become stronger. There are several kinds of infectious diseases. Bacterial infections such as pneumonia(肺炎), are caused by bacteria. these infections can be treated by antibiotics(抗生素), which kill the bacteria. viral
infections are caused by virus, such as the influenza virus. These can sometimes be treated by vaccines, such as flu vaccines. An example of parasitic(寄生虫的) infection is malaria(疟疾). Malaria is caused by parasites transmitted to humans by infected mosquitoes. Once inside the body, the parasites can be difficult to kill or control. And also, these parasites are also
deadly for people age 20 to 40, rather than the elderly and young children. Now a century later, we have flu vaccines that have reduced the severity of the epidemics. These vaccines needed to be updated every year because the virus changes and new strange immerge. What researchers fear is that a new strange will develop and cause another pandemic. Once an outbreak occurs,
transmission of the disease will be even faster than the before. An unattempt consequence of our improved transportation system will be the speed in which an epidemic can spread. Experts predict that the public health systems will be overwhelmed and unable to react quickly enough. So the best defense will be to prevent an outbreak from occurring. This will require global cooperation and
My husband I’m putting too much pressure on him. He thinks it’s wrong thing to do.
I wouldn’t know. I’ve not even married yet. That’s my problem. I wish I had a husband to disagree with.
Well, h e thinks it’s important for kids to have time to be bored.
Bored?
Yes, he really said that. Can you believe it?
Why did he think so? Did he have time to be bored when he was a boy. Well, he grew up in the countryside. He said he had to find things for himself to do. He feel sorry for his kids these day because their days were so structured.
That’s what I told him.
Then he said it’s important to learn how to be independent and not always depend on being told what to do. He said that can develop creativity and the love of learning.
Certainly. What happens when he is behind of oth er kids in school? won’t he be discouraged?
He said he wanted the boy to deal with it and see what happens.
Some people are more competitive and some aren’t.
Anyway, it’s an interesting point of view. It may work for some kids and not for

Hedy Lamarr a Hollywood star and mother of Wi-Fi
Hedy Lamarr was born Hedwig Eva Naria Kiesler in 1914 in Vienna, Austria. By the time she was a teenager, she had decided to drop out of school and seek fame as an actress. She first appeared in a German film in 1930. She
composer(作曲家) George Antheil, whom she met in 1940, she discovered a way to break up signals and transmit them over different frequencies. Using a method similar to the way player piano work, they designed a
frequency-hopping system(跳频系统) that would continually change the radio signals sent to a torpedo. While others, including Nikola Tesla, had explored
similar ideas of frequency hopping, Lamarr and Antheil obtained a patent for their invention in 1942 for what would become known as spread-spectrum(扩频) technology.
Although the US Navy did not adopt the technology during the war, it was used during the Cuban Missile Crisis in 1962. For decades Lamarr’s technology

AI, or artificial intelligence, is another technology that is highly disruptive(破坏的). With AI, smartphone are other devices will have even more capabilities. They will be able to converse with us and tell us jokes. They may even become personal tutors. They will know what kind of problems we have, our
preferences, and any content we want to learn or practice, they will be able to adapt to our needs and be available at any time. And all this will be at less cost than using a human.
In fact, the substitution(替换) of AIs for human labor has the potential to transform our world. Experts warn that smart machines may cause widespread
tasks. Are we up to the task?
Unit 3-3 listening 斯坦福监狱实验
In 1971, psychologist created one of the most important experiment in psychology. The experiment known as the Stanford prison experiment, look at the impact of situation in human behavior. The researchers, led by Philip
Zimbardo, wanted to know how situations could affect how people behave. In participle, we wanted to know if good people would change their personalities and lose their values. In the experiment, participants were divided into 2 groups. One group became prison guards and the other group became prison inmates. The experiment was set up in Stanford university’s psychology
prisoners who needed to be punished for bad behavior. Guards were instructed not to physically harm the prisoners by any way. prisoners were to be addressed by assigned numbers and never by name. to prevent eye contact with the prisoners, guards wore mirror sunglasses. This was done to dehumanize the relation between guards and prisoners. Though the
experiment was designed to last for 14 days, it had to stop after just 6th days. It had to stop because what was happening to the participants. The interactions between the prisoners and guards had become hostile and degrading(有辱人格的). The guards had become aggressive and brutal and the prisoners were passive and depressed. As a result, five of prisoners had to be released early
it is an example of unethical research. It went on longer than it should have. It is also unrepresentative since the participants were mostly white, middle-class, males. Despite the criticism, the experiment remains an important study of human behavior. Recent example of the Stanford effect may include the treatment of prisoners of war by American soldiers in the Iraq War. Other
possible examples including boiling in school and gun behavior. According to the head researcher, *, it helps to explain how ordinary people sometimes turn bullying evil. If situation do influence people behavior, then managing situations can be a way of controlling people.
The prisoners had to remain in prison for the duration of the experiment.

Hi, what’s so urgent. When you message me, you seemed really upset.
Yes, i was. I was confused and I still am. I need your advice. You’ve known me for a long time.
You are my best friend. So what did it?
So why are you asking for advice? If i were to said it’s OK to take the job, will that give an excuse to take it? You otherwise have to live with yourself. Honestly, what would you do?
If i were in your situation, i would probably feel the same way. And to be honest, i hope i would be able to stay true to myself. I suppose if my family were very
poor and in trouble, I’d be tempted. But even then, to betray my friends and colleagues, who would I be. It’s a real test of character.
Yes, those are my thoughts. And I’m not sure what my wife will think.
Look, i know your wife. I think she will be proud of you if you do the right thing. Yes, she probably will. And in the end, I’m not sure i can treat the *. they are a

Unit 3-4 listening 投资买房
John and Linda have been arguing about whether to buy a house for a long time. They have been renting a small flat for several years and the rent keeps going up. Last year, John wasn’t sure about his job situation so they agreed to
delay the decision. They also invested some money in the stock market and their investments are doing well. Linda really wants to have a place of her own. She is growing impatient and doesn’t want to wait any longer. She wants to sell some of their investments and put the money into a nice house. John is against buying now because he thinks prices are too high. He is also worried
would worth. When they lost their jobs, they couldn’t pay the mortgage. They couldn’t sell either, because the selling price was less than what they owed to the bank. So they had to move out and the bank took possession. Now the prices are rising again so the same thing could happen again. A cycle of boom and bust which people tend to forget.
Linda has a different view. She thinks he worries too much. She thinks if they buy now, prices will continue to rise. If they don’t buy now, they will miss the opportunities and regret it later. She isn’t worried by the possibility that the prices may drop in the future.
Anoth er reason John is against buying a house is he doesn’t have confidence
more on research and development. So based on his analysis, the company is OK within for the next year or 2. But beyond that, its future is questionable. As a result, John doesn’t want to buy a house now and take on a huge debt. Until he has more confidence in his situation, he doesn’t want to take the risk. His wife thinks he’s too conservative. She has waited long enough and she doesn’t
want to wait any longer. So John’s dilemma is how to balance his wife’s happiness against the risk of losing a lot of money. One thing for sure now is that s he isn’t happen as things stand now. she’s been waiting for a long time and he loves her. So the decision seems clear. John knows exactly what to do. Maybe some flowers and celebration.
I understand. I’m will to take less than what I’m being paid now but I have 2 children. So I’ve got to consider that too. I need to at least cover our basis living expenses.
OK, we have 2 ways we can do this. Both of them have you starting at a reduced salary. One will give you a bonus after each round of financing. With
the other, you can start with a higher salary but the bonus will be smarter or none at all.
What’s the time for the financing?
That depends on a lot of things. We are hoping to get next round financing with 6 to 9 months. We don’t want to go to our investors because we want to be in a
present job and we could try to bring him in latter. That will lower his risk.
I doubt if h e would consider that, but it’s worth a try.
Yeah, let’s hope it doesn’t come to that. Whatever, we should try to avoid losing him completely.
Well, I’m optimistic. I think he will decide to join us. He’s the kind of guy who likes a challenge.
From I co uld tell, we certainly won’t have to push him to get things done. Exactly. He will feel the pressure just like the rest of us.

The process of implanting the device into Matt was quite involved. First, a circular piece of his skull was removed. Then a tiny plate with hair-thin electrodes(电极) was inserted into his brain. it was placed in the motor
cortex(运动皮层), the brain region that controls movement. This plate detects the electrical signals in the brain that usually control hand movement. From the
plate, thin cables were connected to a small computer which decodes the signals from the plate and converts them into commands. Hopefully, these commands would control the artificial hand attached to Matt’s arm.
Shortly after the operation, Matt was surrounded by the surgeons as he stared at his artificial hand with hope. To the delight of the crowd, the hand started
by investors. Here are some guidelines that may help investors save a lot of money.
First, a key to successful investing is time itself. What makes many investors rich is that they have invested over a long time. This allows their investments to grow, even if they weren’t active investors. Unfortunately, most people don’t
start saving enough until it’s too late. that lack of time limits the power of compounding(积累；混合). So the best advice is to start saving as soon as possible.
What about economic projections and earnings growth estimates? The truth is, nobody knows. What they really reflect are people’s feelings about the future.
interest in your wealth is how much they can charge you. Unfortunately, the louder a financial expert is, the more exposure he will get even though he’s often wrong. This is one of the most important things to know about finance. Don’t be misled by experts.。
